Q: What is the best device to use VisionAssist on?

A: The best device is the one that is most convenient as you always have it with you! Some people prefer to use iPhone or iPod Touch as it is easy to carry with you all the time. Others prefer the large screen of the iPad. Technically, you will get the best image quality from the devices that have the best quality cameras and the fastest CPU. An iPhone 5 or better, or an iPad Air or better is recommended.

Q: Help, VisionAssist only shows a blank screen!

A: From iOS8 onwards Apple includes new Privacy features. If for some reason the VisionAssist screen is blank, please check that VisionAssist can access your camera by reviewing Settings -> Privacy -> Camera -> VisionAssist. Sometimes after an iOS upgrade the privacy settings get reset.

Q: Does VisionAssist support VoiceOver accessibility?

A: VoiceOver is fully supported from v1.2.

Q: Why does the image blur when I move my smartphone?

A: Sometimes the image can blur when you move the smartphone. This can happen on older smartphones with lower speed CPUs. One technique can be to capture the entire image, press pause, then pan the image, adjust colour scheme, etc.
